What Is 4:3 Aspect Ratio And How To Calculate It?

Aspect Ratio

The 4:3 aspect ratio is a rectangular shape that has been used for television screens, computer monitors, and other displays for many years. It is also called the “4:3” or “Four-to-Three” ratio. The 4:3 aspect ratio was introduced in the mid-1950s and replaced the old square format screens.

The 4:3 aspect ratio, also known as a “full screen” aspect ratio, is the most common screen shape. This means that all of your favorite TV shows and movies use this aspect ratio.

It’s also the standard for HDTVs, which makes it a good choice if you’re looking to watch video content in its native format. However, if you want to watch 16:9 content on your 4:3 screen, you’ll need to use black bars above and below the picture (called letterboxing).

This article will help you get familiar with this kind of aspect ratio in case you have to work with it.

What is the 4:3 aspect ratio?

The 4:3 aspect ratio, or full aspect ratio, is a display aspect ratio of 4 units wide to 3 units high. It is most commonly used in standard-definition television and analog computer displays. The 4:3 aspect ratio allows the same image to be displayed with a minimum of distortion on both standard- and high-definition television screens and computer monitors.

4:3 is commonly used in digital cameras, which use sensors that are generally taller than they are wide. This same shape is used for 35mm film frames. It is also common in motion pictures since it allows more people to fit into a frame without having to pan or scan a shot

What are the benefits of using the 4:3 Aspect Ratio?

The 4:3 aspect ratio has been used in film since the beginning of cinema. It’s been so widely used that it’s often referred to as the “classical” or “cinematic” aspect ratio. The 4:3 aspect ratio is also called 1.33:1, as it is four units wide by three units high.

The benefits of using this aspect ratio in your videos include:

Simplicity. The 4:3 ratio is very simple and easy to understand, so you can focus on telling your story rather than on explaining how your video works.

Usability across a variety of devices. Videos with 4:3 aspect ratios tend to be viewed on both large and small screens, making them more versatile than other formats such as 16:9 or 16:10 that are optimized for specific displays.

Familiarity with traditional TV shows and movies. Most people are accustomed to watching content in this format, so they’ll feel comfortable when viewing your videos online or through social channels like Facebook and YouTube (which also default to this aspect ratio).

What is the difference between 4:3 and 16:9?

Most of the time, the difference between 4:3 and 16:9 is that the former is square and the latter is rectangle. So, what’s so special about that? Well, it’s all about the ratio of height to width; 4:3 has a 1:1 ratio while 16:9 has a 1.77:1 ratio.

The aspect ratio refers to how much horizontal space there is compared to vertical space on a display or in an image. In the video, aspect ratio determines the shape of the frame whether it’s tall and thin or short and wide which in turn impacts how much information can be displayed in each frame (and thus how many frames can be displayed per second).

Technically speaking, both 4:3 and 16:9 are referred to as “square” formats because they’re both 1:1 aspect ratios (meaning that if you divide either dimension by its height or width, you’ll get an integer). However, 16:9 is more commonly referred to as “widescreen” because it offers more horizontal viewing space than 4:3 does (though not quite as much as 21:9).

How to change the aspect ratio from 16:9 to 4:3?
